Barry:

I read the SB. The gap between the front and rear halves of the hub was within spec, but I was not the original owner, so according to the SB I should have sent it to GSC for inspection. I ...

There was a single hard shake/knock/bang and the engine stopped. We discovered that that it instantly shook both carbs off. We did not think that there was an overspeed, but the wreck, including the ...

Regarding your question about my prop failure; it was a 2 year old GSC 3 blade. All three blades departed the hub at the same time while cruising at about 2600 feet.

The NTSB studied the remains ( ...

I had a problem similar to yours one time after a carb rebuild. The enriching circuits (chokes) were installed backward. Either upside down or on the wrong carbs, I forget which. The result was tha ...

Thank you all for the referrals and good advice. I have hired a Kitfox builder/owner in New York to look the project and the paperwork over for me.

Mike:

According to the FAA, I only have to show that 51% of the airplane was built by amateurs. Not that I personally built 51% of it. The limitation is that since I personally didn't build the m ...

Although I live in Calif. I have placed a deposit on a Kitfox 5 project in Scarborough, Ontario Canada. The project is complete up to, but not including, the covering stage. Almost all of the assemb ...

Many thanks to those who bought items from my "Many Kitfox related items for sale" list. I still have the cabin cover, seat booster pads and a couple of smaller items.

I lost my beloved Kitfox IV 912 in an off-runway landing and now I need to raise some money by selling the Kitfox and Rotax items that I no longer need.

I purchased a Kitfox IV with a two year old GSC three blade prop. The hubs came together at just under 100 in/lb. After researching the problem, I had the hubs milled .005, then torqued the bolts to ...

The enriching circuits (chokes) on the left and right carbs are mirror images of each other. When I first got my 912 someone had reversed them, which made them "off" at idle and "on&qu ...

I did the same thing. You can run them into the filters, but the low pressure there will cause the float chambers to overfill. My engine installation manual says to leave them at the original length ...

Glenn:

I think we know what you meant, but there is a lot of confusion here (and everywhere, it seems) concerning the LSA/Sport Pilot rules. Let's try and keep the jargon straight.

There is no ...

No we did not find the blades. We were at 2700 ft, entering a mountain pass when they departed. We did a 180 and glided 3 or 4 miles away before landing. The local police said that they had no repo ...

Dave:

The prop was 3 years old and had a about 90 hours on it. The separation between the prop hub halves was within spec at the last condition inspection.

The NTSB has the hub now, so we'll ...

Hi all:

I am sad to report that my beautiful Model IV Speedster was destroyed last week in a forced landing caused by the GSC prop.

All three blades departed the airplane in straight and level c ...

Well, if the EAA is not authoritative enough for you, let's try the FAA's own documents. This is from the faa.gov website:

Regulations (Parts 43 and 91)

There seems to be some confusion here between the rules covering ELSA aircraft and Experimental, Amateur-Built aircraft. With regard to the latter; here is a quote from the EAA website:

I am going ...

Jack:

I went through the same thing when I needed to replace the choke cables. I just needed to replace the inner cable, since the sleeves were OK. The cables I bought locally and online proved t ...
